WebAlveolar ventilation (V) is the amount of air that reaches alveoli in the lungs, measured in liters/minute (L/min); and perfusion (Q) is the pulmonary blood flow, or cardiac output, that reaches the arteries, and specifically the capillaries, surrounding the alveoli, also measured in L/min. . When the lungs are upright and at rest, ventilation is about 4 L/min and …
